Coronary CT angiography with calcium score is done to detect the presence of calcium deposits in the coronary arteries and to check for blockages that may be causing symptoms such as chest pain or shortness of breath. This test can help in the diagnosis of coronary artery disease and help guide treatment decisions.
When this test is required
This test may be requested if you have symptoms of heart disease or if you have risk factors for coronary artery disease. It may also be ordered to monitor the progression of coronary artery disease or to assess the effectiveness of treatment.
What the Test Detects
This test combines a coronary CT angiogram with a calcium score to evaluate the coronary arteries for blockages and calcium deposits. The coronary CT angiogram uses contrast dye and special X-ray imaging to create detailed pictures of the coronary arteries. The calcium score measures the amount of calcium in the coronary arteries, which is an indicator of plaque buildup.
Preparation for the Test
Before the test, you will be asked to fast for a few hours. You may also be asked to avoid caffeine and certain medications. You should inform your doctor if you have a history of allergies, kidney problems, or thyroid problems.
Sample Requirements
No sample is required for this test.
Additional Notes
The contrast dye used in this test may cause an allergic reaction in some people. You should inform your doctor if you have a history of allergies or kidney problems. The test involves exposure to radiation, so it is important to discuss the risks and benefits with your doctor.
